Deformation Behaviour of Erodible Soil Stabilized with
In this research, quarry dust is used in combination with cement to reduce the cost and brittleness. Secondly, the massive mining of sand for construction leads to change in ecosystem thereby triggering global warming. Quarry dust, being an industrial waste from quarry mines, is good replacement for sand in road construction [21, 22].The findings showed that the partial replacement of cement with quarry dust is not detrimental to product durability and the recycled material qualifies as a strength class 42.5, type II/A binder. The materials bearing 20% granite quarry dust, in turn, were found to meet the requirements to qualify as low heat cements (CEM II/A LH).Durability of new recycled granite quarry dust-bearing cements

A Study on Mechanical Properties of Concrete Incorporating
Aluminum dross, cement, sand, and quarry dust were used in a variety of proportions with a constant percentage of fly ash for the design of nine concrete mixtures. Aluminum dross was replaced by 5, 10, 15, and 20% of the cement mass. At first, the optimum replacement of aluminum dross without using quarry dust was determined at a dust, granite dust, crushed rock dust and lime stone powder commonly referred as quarry dust, is produced from stone processing industries and is an inert material, generally used for land filling, creating conservational problems [3, 4].
